To all whom t may] concern Be it known that I, Cie-xmms B. Sortons- MnnL, citizen of the United States, and resident of Waterbury, in the county ot New Haven and State of Connecticut, have invented certain new and useful Improvements in Galvanie Batteries, of -which the following is a specification.

My invention relates to improvements in galvanio batteries, and particularly to that type of battery employing plate forms ot copper oxid and zinc electrodes. 'lhe invention particularly refers to improvements in supporting means 'for both said electrodes, whereby the said copper oxid plate as well as the co-acting zinc or positive electrodes may be properly supported on the traine and from the cover of a jar7 by asingle slipporting roti The purposes of the invention are first to provide a combined frame and hanger Vfor compressed oXid ot copper negative plate electrodes whereby an improved contact of the frame with the plate insured and whereby irregularities of shape duc to shrinkage or warping may be compensated t'or, thus enabling all negative plates ot a supposedly fixed size being readily insertedinto the frame Without the necessity ot grinding or fitting,- the plates; to so construct the device that the hanger propel.' can be employed or used over and over again, and wiii permit of the insertion ot new piates; to provide n, frame which will proteet and strengthen. the plates, rendering them less liable to break 1n shipment and handling; and second to provide a new form ot' insulatingr bloeit upon the frame and to which an im' roved construction of positive plate is rigid y attached. l

Other objets 01"' the invention will hereru after appear and. to these ends the invention consists in a battery frame for carrying out the above objects; embodyingl the 'features of /eonstruetiong combination ot elements and, arrangement of parts havingr the general. Inode of operation substantially as hereinafterf'tully described and claimed in the speeilication and claims and shown in the accompanying'drawings in which,

Figitrel, shows a perspective view of my improved,form of battery electrode hanger and platetraine with the negative or com pressed 'oopper oxid plate. contained therein. Fig. 'Q a side edge View partially in seetmn ofitheitrame with the positive or zine plate l electrode attached to the sides thereof. Fig. I

3 is a perspective view of the said negative compressed copper oxid plate electrode with edge or traine strips attached and ready for msertion into the hanger. .Figfel is a perspective. view of one of the side channel strips ot' plate frame, detached, Fig. 5, is a turthcr perspective view of the top and bottom channel strips of plate frame as einu ployed on the nee'ative electrode shown in lfig. 3. Fig. 6,` sdiows a detached perspective view of one of the :cine or positive plates shown in Fig. 2, and, Fig. 7, shows a modified forni of hanger and plate framefor a round compressed oxid plate.

Upon the drawings represents a suspending rod by means of which the hanger, trame and attached electrode, constituting the assembled element7 are suspended from the cover or bridge ot a battery jar, not shown. The lower end of this suspending rod is provided with a head 7 und a nut` 8 whereby the said rod is made fast to a strip 9 passing over an. insulating bloeit l0. This block is sup ported upon the reetangular hanger 1l the top port-ion of which is secured to the before mentioned strip E) by ineens of suitable rivets 1Q at either side of the porcelain bloeit l0. This hanger ll is thus formed of a plain flat piece of sheet metal, bent into a rectangular form and haring its two end portions brought tolggothcr central ot the top as shown at le in dotted lines in Fig. l, und there covered by the before mentioned porcelain block l() which straddles the said strip. The width ot thc strip of which the hanger is 'toi-mcd is substantially the saine as that o't' the thickness ol the ueg'ativeplato 1.7 and is 'termed with smooth side edges which permit the plate to be inserted t'roni either side. rlhe under central portion o'f the porcelain bloot: is provided with a longitudinal recess 13 to rece-ive the hanger frame and plate and to hold the block in position intermediete ot the said top cross member of the hanger, und the before mentioned strip 9. The opposite under outer edge portions of the block rare cut away as shown in Figs. 1 and 2 to form a shoulder 222 against which the top central edge portieri of the :Lino plates are secured. Vin eaeh outer side of the block is also formed elongated a vertical recess to receive the brass upporting stein 24 cast in the upper central portion or" the zinc plates. A holo .5 is formed through these stems as shown, to register with the sull nolo 14 through the block. A. bolt 26 is passed through the stems ot the plates and the hole in the block, and is provided with nuts or securing the parts iirmly together in the manner shown in 2. l The foregoing construction obviously insures a rigid attachment ot the positive plates to the porcelain and true alinement of the -saitl positive with the negative plates, and also durable connection between the said zinc platesand bolt, that will not be affected and destroyed in use.

The negative plate electrode which is designated as 17 may he formed with plain Aliat Asides or be provided with beveled edges as preferred9 and further be of such other size and proportion may be deemed advisable.-

l employ suitable sheet metal channel strips i8 and 19 to cover the several edges of the negative electrodeplate in the manner shown in Fig. 3, and thus produce an inexpensive form of frame which in practice closely hugs the edge portion ot ,the plate in a manner to form a good and suiiicicnt eleetrieal contact between the plate and its trame as well as the hanger ll. in which the plate and frame are removably supported. This trame as shown in the preferred forms is formed of Ytour channel strips, the top and bottom ones ot which are alike in construction and designated as 18. The side menibers 19-19 arev also alike and have theirl side flanges cut away slightly adjacent to their end portions leaving the central or body portion extended slightly to torni the central extensions 2O as shown in Figs. and 5. The intermediate portions ot the ends ot' the top 1S are eut away to form the side flange extensions 2l which are easily bent over upon the sides ot the hanger. These plate trame men'ibers are laid together upon the respective edges of the electrode 17 inv the manner shown in Fig. 3, with the end vflange extensions 2l bent out to one side at substantially a right angle. This leaves the plate and frame in 'lorin to be plaeed in the lninger which operation is obviously simple,

. since the size ot the plate with removable sti-ips, constituting its trame, are just right to tit snugly into the tour walls oif the hanger, the top edge of the plate being` first inserted to engage the recess in the under side ot the block whereupon the remaining portion ot the plate is likewise slipped into lposition. This leaves the extensions 2l upon the one 4side disposed straight outward in their original forni and the opposite extensions at a rightangle as shown at the upper corners in Fig. l. Both ot these extensions are thereupon bent over upon the outside of the hanger in the manner shown. at the lower corners in Fig. l, thereby Yfirmly sevcuring the plate and its frame together in position within the hanger. It it be desired at any time to remove the plate it can be :nosofisa readily done by first bending back the four extensions on one side and then shoving the plate out from the hanger so that a renewal may be inserted if desired.

in. Fig.- 7, I have shown a hanger adapted to support a round annular plate when mounted in a frame hung in a plain Hat circular form of hanger lla that is made of one piece ot sheet metal. An insulating block l() similar to that shown in Figs. l" and 2 is mounted upon the hanger and frame and secured by means of the before inentioned attached strip 9 which is provided with a suspending rod 6. The plate trame 18a in this form is made of a single'length Iof sheet metal channel strip which is curled around to engage the edges of the plate. rllhe plate and trame are supported within the hanger at the top by means of the before mentioned insulating block and at the bot tom by a small piece of sheet nietal 21a se cured to the hanger and having extensions that are `bent up against the sides of the plate iframe.

l-i'aving thus described my invention what l claim and desire to secure by Letters `Patent isl.. ln an electrode support tor batteries, the emnbination ot a sheet metal hanger, an insulating block mounted upon the hanger, a strip passing over the block and having its ends secured to the hanger a plate electrode, a metal frame engaging the edges of the electrode and adapted to be supported within the h anger, and means for securing the plate and `frame in said hanger.
